I am working on a reporting library (perhaps a gem someday). It's coming along pretty well thus far, though I could use some collective intelligence on something.
I would like ActionView::Base (particularly the helpers to be available within a lambda. The point of this is to define transformations on columns (0..n) within an instance of the class to output within an erb template.
For reference, both class A and B below produce the correct result, but class C is what I'm trying to do.
class A < ActionView::Base def run content_tag('a','b') end end
class B < ActionView::Base def run l = lambda { content_tag('a','b') } l.call end end
class C < ActionView::Base attr_accessor :l
def run l.call end end
a = A.new => #<A:0xb35c9a00 @controller=nil, @assigns_added=nil, @assigns={}, @view_paths=, @logger=nil> a.run => "<a>b</a>"
b = B.new => #<B:0xb35c60f8 @controller=nil, @assigns_added=nil, @assigns={}, @view_paths=, @logger=nil> b.run => "<a>b</a>"
c = C.new => #<C:0xb35c37b8 @controller=nil, @assigns_added=nil, @assigns={}, @view_paths=, @logger=nil> c.l = lambda { content_tag('a','b') } => #<Proc:0xb35bf938@(irb):26> c.run NoMethodError: undefined method `content_tag' for #<Object:0xb7d249a4> from (irb):26 from (irb):18:in `call' from (irb):18:in `run' from (irb):27
Any thoughts?
